Mouse IgG3 isotype control antibody

Mouse IgG3 isotype control (natural and engineered mIgG3 isotype controls) are useful for in vitro and in vivo studies from ELISA, Western blot (WB), to cell-based assay to animal model study.  

Please contact us to ask for a quote for the Fc silenced mouse IgG3 isotype control mutants, mIgG3 isotype control and mutants with Avi-, His-, and Flag-tags, and biotinylated mIgG3 isotype control and mutants. A variety of conjugates (such as dyes and fluorophores) with the mouse IgG3 isotype control and Fc-slient mutants are available.

Background

Mouse IgG antibodies are classified to four subclasses mainly based on the isotype of the heavy chain (IgG1, IgG2a or IgG2c, IgG2b, and IgG3 for the heavy chain; kappa and lamda for the light chain), of which IgG1 and kappa are the most abundantnamed in serum. IgG antibodies are large molecules of about 150 kDa composed of four peptide chains, two identical heavy chains of about 50 kDa and two identical light chains of about 25 kDa. The four peptides are arranged in a Y-shape tetramer by disulfide bonds formed between the two heavy chains and between a heavy chain and a light chain.
